1. Multi-scale modeling and simulation of thermoplastic automated tape placement: Effects of metallic particles reinforcement on part consolidation

Abstract: This paper concerns engineered composites integrating metallic particles to enhance thermal and electrical properties. However, these properties are strongly dependent on the forming process itself that determines the particle distribution and orientation. At the same time, the resulting enhanced thermal properties affect the reinforced resin viscosity whose flow is involved in the intimate contact evolution. Thus, a subtle and intricate coupling appears, and the process cannot be defined by ignoring it. In this paper, we analyze the effects of particle concentration and orientation on the process and processability. For this purpose, three main models are combined: (i) a multi-scale surface representation and its evolution, by using an appropriate numerical model, (ii) flow-induced orientation, and (iii) the impact of the orientation state on the homogenized thermal conductivity.

Abstract: The problem of detecting loops in a forwarding network is known to be NP-complete when general rules such as wildcard expressions are used. Yet, network analyzer tools such as Netplumber (Kazemian et al., NSDI'13) or Veriflow (Khurshid et al., NSDI'13) efficiently solve this problem in networks with thousands of forwarding rules. In this paper, we complement such experimental validation of practical heuristics with the first provably efficient algorithm in the context of general rules. Our main tool is a canonical representation of the atoms (i.e. the minimal non-empty sets) of the field of sets generated by a collection of sets. This tool is particularly suited when the intersection of two sets can be efficiently computed and represented. In the case of forwarding networks, each forwarding rule is associated with the set of packet headers it matches. The atoms then correspond to classes of headers with same behavior in the network. We propose an algorithm for atom computation and provide the first polynomial time algorithm for loop detection in terms of number of classes (which can be exponential in general). This contrasts with previous methods that can be exponential, even in simple cases with linear number of classes. Second, we introduce a notion of network dimension captured by the overlapping degree of forwarding rules. The values of this measure appear to be very low in practice and constant overlapping degree ensures polynomial number of header classes. Forwarding loop detection is thus polynomial in forwarding networks with constant overlapping degree.

Abstract: International audience; Speaker diarization has become a key process within other speech processing systems which take advantage of single-speaker speech signals. Furthermore, finding recurrent speakers among a set of audio recordings, known as cross-show diarization, is gaining attention in the last years. Current state-of-the-art-systems provide good performance, but usually at the cost of long processing times. This limitation may make current systems not suitable for real-life applications. In this line, the speaker diarization approach based on binary key modeling provides a very fast yet accurate alternative. In this paper, we present the last improvements applied in binary key speaker diarization with the aim of further speeding up the process and improving performance. In addition, we propose a novel method for cross-show speaker di-arization based on binary keys. Experimental results show the effectiveness of the proposed improvements for single-show speaker diarization, both in terms of speed and performance, obtaining a real-time factor of 0.0354xRT and a 16.8% relative improvement in performance. Furthermore, our proposed cross-show approach provides very competitive performance, just slightly worse than its single-show diarization counterpart, and exhibits a real time factor of 0.04xRT. Index Terms-Binary key speaker modeling, cross-show speaker diarization, speaker diarization, within-class sum of squares.

Abstract: International audience; In recent years, the progress in both hardware and software allows user-space applications to capture packets at 10 Gb/s line rate or more, with cheap COTS hardware. However, processing packets at such rates with software is still far from being trivial. In the literature, this challenge has been extensively studied for network intrusion detection systems, where per-packet operations are easy to parallelize with support of hardware acceleration. Conversely, the scalability of statistical traffic analyzers (STAs) is intrinsically complicated by the need to track per-flow state to collect statistics. This challenge has received less attention so far, and it is the focus of this work. We present and discuss design choices to enable a STA to collects hundreds of per-flow metrics at a multi-10-Gb/s line rate. We leverage a handful of hardware advancements proposed over the last years (e.g., RSS queues, NUMA architecture), and we provide insights on the trade-offs they imply when combined with state-of-the-art packet capture libraries and the multi-process paradigm. We outline the principles to design an optimized STA, and we implement them to engineer DPDKStat, a solution combining the Intel DPDK framework with the traffic analyzer Tstat. Using traces collected from real networks, we demonstrate that DPDKStat achieves 40 Gb/s of aggregated rate with a single COTS PC

Abstract: The great success and widespread use of impregnated diamond (ID) bits are due to their self-sharpening mechanism, which consists of a constant renewal of diamonds acting at the cutting face as the bit wears out. It is therefore important to keep this mechanism acting throughout the lifespan of the bit. Nonetheless, such a mechanism can be altered by the blunting of the bit that ultimately leads to a less than optimal drilling performance. For this reason, this paper aims at investigating the applicability of artificial intelligence-based techniques in order to monitor tool condition of ID bits, i.e. sharp or blunt, under laboratory conditions. Accordingly, topologically invariant tests are carried out with sharp and blunt bits conditions while recording acoustic emissions (AE) and measuring-while-drilling variables. The combined output of acoustic emission root-mean-square value (AErms), depth of cut (d), torque (tob) and weight-on-bit (wob) is then utilized to create two approaches in order to predict the wear state condition of the bits. One approach is based on the combination of the aforementioned variables and another on the specific energy of drilling. The two different approaches are assessed for classification performance with various pattern recognition algorithms, such as simple trees, support vector machines, k-nearest neighbour, boosted trees and artificial neural networks. In general, Acceptable pattern recognition rates were obtained, although the subset composed by AErms and tob excels due to the high classification performances rates and fewer input variables.

Abstract: Because of the lack of Multipath TCP (MPTCP) support at the server side, some service providers now consider a network-assisted model that relies upon the activation of a dedicated function called MPTCP concentrator. This document focuses on a deployment scheme where the identity of the MPTCP concentrator(s) is explicitly configured on connected hosts. This document specifies an MPTCP option that is used to avoid the encapsulation of packets and out-of-band signaling between the CPE and the MPTCP concentrator. Also, this document specifies how UDP traffic, in particular, can be distributed among available paths by leveraging MPTCP capabilities.

Abstract: International audience; Speaker diarization is the task of determining "who spoke when?" in an audio or video recording that contains an unknown amount of speech and also an unknown number of speakers. Initially, it was proposed as a research topic related to automatic speech recognition, where speaker diarization serves as an upstream processing step. Over recent years, however, speaker diarization has become an important key technology for many tasks, such as navigation, retrieval, or higher-level inference on audio data. Accordingly, many important improvements in accuracy and robustness have been reported in journals and conferences in the area. The application domains, from broadcast news, to lectures and meetings, vary greatly and pose different problems, such as having access to multiple microphones and multimodal information or overlapping speech. The most recent review of existing technology dates back to 2006 and focuses on the broadcast news domain. In this paper we review the current state-of-the-art, focusing on research developed since 2006 that relates predominantly to speaker diarization for conference meetings. Finally, we present an analysis of speaker diarization performance as reported through the NIST Rich Transcription evaluations on meeting data and identify important areas for future research.

Abstract: The advent of geolocated information and communication technologies opens the possibility of exploring how people use space in cities, bringing an important new tool for urban scientists and planners, especially for regions where data are scarce or not available. Here we apply a functional network approach to determine land use patterns from mobile phone records. The versatility of the method allows us to run a systematic comparison between Spanish cities of various sizes. The method detects four major land use types that correspond to different temporal patterns. The proportion of these types, their spatial organization and scaling show a strong similarity between all cities that breaks down at a very local scale, where land use mixing is specific to each urban area. Finally, we introduce a model inspired by Schelling's segregation, able to explain and reproduce these results with simple interaction rules between different land uses., Partial financial support was received from the Spanish Ministry of Economy (MINECO) and FEDER (EU) under project INTENSE@COSYP (FIS2012-30634), and from the EU Commission through projects LASAGNE and INSIGHT.

Abstract: The recently proposed speaker diarization technique based on binary keys provides a very fast alternative to state-of-the-art systems. However, this speed up has the cost of a little increase in Diarization Error Rate (DER). This paper proposes a series of improvements to the original algorithm with the aim to get closer to state-of-the-art performance. First, several alternative similarity measures between binary key speaker/segment models are introduced. Second, we perform a first attempt at applying Intra-Session and IntraSpeaker Variability (ISISV) compensation within the binary diarization approach through the Nuisance Attribute Projection.

Abstract: Acoustic fingerprinting is the process to deterministically obtain a compact representation of an audio segment, used to compare multiple audio files or to efficiently search for a file within a big database. Recently, we proposed a novel fingerprint named MASK (Masked Audio Spectral Keypoints) that encodes the relationship between pairs of spectral regions around a single spectral energy peak into a binary representation. In the original proposal the configuration of location and size of the regions pairs was determined manually to optimally encode how energy flows around the spectral peak. Such manual selection has always been considered as a weakness in the process as it might not be adapted to the actual data being represented. In this paper we address this problem by proposing a unsupervised, data-driven method based on mutual information theory to automatically define an optimal MASK fingerprint structure. Audio retrieval experiments optimizing for data distorted with additive Gaussian white noise show that the proposed method is much more robust than the original MASK and a well known acoustic fingerprint.

Abstract: © 2015 Macmillan Publishers Limited. All rights reserved. The extraction of a clear and simple footprint of the structure of large, weighted and directed networks is a general problem that has relevance for many applications. An important example is seen in origin-destination matrices, which contain the complete information on commuting flows, but are difficult to analyze and compare. We propose here a versatile method, which extracts a coarse-grained signature of mobility networks, under the form of a 2 × 2 matrix that separates the flows into four categories. We apply this method to origin-destination matrices extracted from mobile phone data recorded in 31 Spanish cities. We show that these cities essentially differ by their proportion of two types of flows: integrated (between residential and employment hotspots) and random flows, whose importance increases with city size. Finally, the method allows the determination of categories of networks, and in the mobility case, the classification of cities according to their commuting structure., The research leading to these results has received funding from the European Union Seventh Framework Programme FP7/2007-2013 under grant agreement 318367 (EUNOIA project).

Abstract: International audience; Distributing long-tail content is a difficult task due to the low amortization of bandwidth transfer costs as such content has limited number of views. Two recent trends are making this problem harder. First, the increasing popularity of user-generated content and online social networks create and reinforce such popularity distributions. Second, the recent trend of geo-replicating content across multiple points of presence spread around the world, done for improving quality of experience (QoE) for users. In this paper, we analyze and explore the tradeoff involving the "freshness" of the information available to the users and WAN bandwidth costs, and we propose ways to reduce the latter through smart update propagation scheduling, by leveraging on the knowledge of the mapping between social relationships and geographic location, the timing regularities and time differences in end user activity. We first assess the potential of our approach by implementing a simple social-aware scheduling algorithm that operates under bandwidth budget constraints and by quantifying its benefits through a trace-driven analysis. We show that it can reduce WAN traffic by up to 55% compared to an immediate update of all replicas, with a minimal effect on information freshness and latency. Second, we build TailGate, a practical system that implements our social-aware scheduling approach, which distributes on the fly long-tail content across PoPs at reduced bandwidth costs by flattening the traffic. We evaluate TailGate by using traces from an OSN and show that it can decrease WAN bandwidth costs by as much as 80% and improve QoE. We deploy TailGate on PlanetLab and show that even in the case when imprecise social information is available, it can still decrease by a factor of 2 the latency for accessing long-tail YouTube videos.

Abstract: The pervasive use of new mobile devices has allowed a better characterization in space and time of human concentrations and mobility in general. Besides its theoretical interest, describing mobility is of great importance for a number of practical applications ranging from the forecast of disease spreading to the design of new spaces in urban environments. While classical data sources, such as surveys or census, have a limited level of geographical resolution (e.g., districts, municipalities, counties are typically used) or are restricted to generic workdays or weekends, the data coming from mobile devices can be precisely located both in time and space. Most previous works have used a single data source to study human mobility patterns. Here we perform instead a cross-check analysis by comparing results obtained with data collected from three different sources: Twitter, census, and cell phones. The analysis is focused on the urban areas of Barcelona and Madrid, for which data of the three types is available. We assess the correlation between the datasets on different aspects: the spatial distribution of people concentration, the temporal evolution of people density, and the mobility patterns of individuals. Our results show that the three data sources are providing comparable information. Even though the representativeness of Twitter geolocated data is lower than that of mobile phone and census data, the correlations between the population density profiles and mobility patterns detected by the three datasets are close to one in a grid with cells of 2×2 and 1×1 square kilometers. This level of correlation supports the feasibility of interchanging the three data sources at the spatio-temporal scales considered., Partial financial support has been received from the Spanish Ministry of Economy (MINECO) and FEDER (EU) under projects MODASS (FIS2011-24785) and INTENSE@COSYP (FIS2012-30634), and from the EU Commission through projects EUNOIA, LASAGNE and INSIGHT.

Abstract: We design, develop, validate, and deploy WTF (Where's The Fault?), a system that determines whether a performance problem in a home network lies with the ISP or inside the home network. WTF uses four independent maximum like- lihood detectors to detect both access link bottlenecks and wireless network pathologies with high detection rates and low false positive rates; we use extensive controlled exper- iments to determine the appropriate thresholds for each pa- rameter that we measure. We implemented WTF as cus- tom firmware that runs in an off-the-shelf home router and deployed it in 64 home networks across 15 countries. The real-world deployment sheds light on common pathologies that occur in home networks. We find that wireless bottle- necks are significantly more common than access link bot- tlenecks, that the 5 GHz spectrum consistently outperforms the 2.4 GHz spectrum, that many homes experience high TCP round-trip latencies between wireless clients and the ac- cess point, and that performance can vary dramatically across wireless devices, even within a single home network.

Abstract: International audience; The ACM 8th international conference on emerging Networking EXperiements and Technologies (CoNEXT) was or- ganized in a lovely hotel in the south of France. Although it was in an excellent location in the city center of Nice with views to the sea, it suffered from poor Internet connectivity. In this paper we describe what happened to the network at CoNEXT and explain why Internet connectivity is usually a problem at small hotel venues. Next we highlight the usual issues with the network equipment that leads to the general network dissatisfaction of conference attendees. Finally we describe how we alleviated the problem by offloading network services and all network traffic into the cloud while supporting over 100 simultaneous connected devices on a single ADSL link with a device that is rated to only support around 15-20. Our experience shows that with simple offloading of certain network services, small conference venues with limited budget no longer have to be plagued by the usual factors that lead to an unsatisfactory Internet connectivity experience.

Abstract: International audience; This article explores the possibility of using traffic optimization techniques within the context of the LISP (Locator/ Identifier Separation Protocol) framework. These techniques use Tunneling, Multiplexing and header Compression of Traffic Flows (TCMTF) in order to save bandwidth and to reduce the amount of packets per time unit. Taking into account that encapsulation is necessary in LISP, bandwidth can be drastically reduced in flows using small packets, which are typical of many real-time services. The ability of the LISP framework to manage the signaling of TCMTF options is also studied. An analytical expression of the savings, as a function of the different header sizes, is devised and used to calculate the maximum expected savings. Different services and scenarios of interest are identified, and this allows the consideration of tests with real traffic traces, showing the savings as a function of the multiplexing period, and demonstrating that the additional delays can be acceptable for real-time services.

Abstract: This document describes StratusLab's plans for exploitation and sustainability be- yond the project lifetime. The plans cover commercial exploitation, primarily through commercial integration and support; and non-commercial exploitation, through use in national and international research e-infrastructures: for operating grid resources on private clouds, and for running research-oriented community clouds. In addition, we plan exploitation through partner projects such as EGI and through training and future research. Plans are in place to ensure the sustainability of the critical infrastructures used by the project partners, users and collaborating projects. Similarly, the software outputs of the project have been identified and a plan for the future development of each has been created. These plans include the formation of an open-source StratusLab community, identifying key partners to continue development of specific components, identifying funding options (public, private and community contributions) for continued development and engaging with collaborating projects to ensure that they will contribute to the maintenance and development of the components that they use.

Abstract: International audience; Distributing long-tail content is an inherently difficult task due to the low amortization of bandwidth transfer costs as such content has limited number of views. Two recent trends are making this problem harder. First, the increasing popularity of user-generated content (UGC) and online social networks (OSNs) create and reinforce such popularity distributions. Second, the recent trend of geo-replicating content across multiple PoPs spread around the world, done for improving quality of experience (QoE) for users and for redundancy reasons, can lead to unnecessary bandwidth costs. We build TailGate, a system that exploits social relationships, regularities in read access patterns, and time-zone differences to efficiently and selectively distribute long-tail content across PoPs. We evaluate TailGate using large traces from an OSN and show that it can decreaseWAN bandwidth costs by as much as 80% as well as reduce latency, improving QoE. We deploy TailGate on PlanetLab and show that even in the case when imprecise social information is available, TailGate can still decrease the latency for accessing long-tail YouTube videos by a factor of 2.

Abstract: The document describes the updated Reference Architecture for StratusLab v2.0, building on D4.1, which described the architecture for StratusLab v1.0. This document contains two main parts, the overall architecture identifying the required services and components of which it is composed, followed by detailed descriptions for each of these elements. For v2.0, the architecture is rationalized and consolidated. For example, the policy validation, caching and cloud storage are integrated as default features. The Appliance Repository is replaced by the cloud storage service. Several services are also added, such as cloud storage, virtual network provisioning and inter-cloud connectivity. From v1.0 to v2.0, incremental versions of the StratusLab distribution will be built and released to provide an increasing amount of the functionality identified in this document, alongside further improvements to the robustness of the distribution.

Abstract: This document describes StratusLab's plans for exploitation and sustainability during the second year of the project and beyond. The plans cover commercial exploitation, primarily through commercial integration and support; and non-commercial exploitation, through use in national and international research e-infrastructures: for operating grid resources on private clouds, and for running research-oriented community clouds. In addition, we plan exploitation through projects such as OpenNebula and EGI, and through training and future research. Sustainability is driven by a desire to support critical infrastructures and as a basis for future research. Public funding, private funding and community contributions will play a role in sustainability through promotion, community development, support of cloud strategies, national cloud infrastructures, and cloud research.

Abstract: Dynamic Time warping, Multimedia indexing, speech processing; International audience; The automatic summarization of speech recordings is typically carried out as a two step process: the speech is first decoded using an automatic speech recognition system and the resulting text transcripts are processed to create the summary. However, this approach might not be suitable with adverse acoustic conditions or languages with limited training resources. In order to address these limitations, we propose in this paper an automatic speech summarization method that is based on the automatic discovery of patterns in the speech: recurrent acoustic patterns are first extracted from the audio and then are clustered and ranked according to the number of repetitions in the recording. This approach allows us to build what we call a "Spoken WordCloud" because of its similarity with text-based word-clouds. We present an algorithm that achieves a cluster purity of up to 90% and an inverse purity of 71% in preliminary experiments using a small dataset of connected spoken words.

Abstract: International audience; In recent years there has been a trend for more user participation in Internet-based services leading to an explosion of user-generated, tailored, and reviewed content and social-networking- based applications. The next generation of applications will continue this trend and be more interactive and distributed, putting the prosumers at the center of a massively multiparticipant communications environment. Furthermore, future networked media environments will be high-quality, multisensory, multi-viewpoint and multistreamed, relying on HD and 3D video. These applications will place unprecedented demands on networks between unpredictable and arbitrarily large meshes of network endpoints. We advocate the development of intelligent cross-layer techniques that, on one hand, will mobilize network and user resources to provide network capacity where it is needed, and, on the other hand, will ensure that the applications adapt themselves and the content they are conveying to available network resources. This article presents an architecture to enable this level of cooperation between the application providers, the users, and the communications networks so that the quality of experience of the users of the application is improved and network traffic optimized.

Abstract: Splitting a speech signal into speakers is the main goal of a speaker diarization system, which has become an important building block in many speech processing algorithms. Current state of the art systems are able to obtain good diarization error rates, but most of them are rather slow, which is a strong handicap in applications that require overall faster than real-time processing. In this paper we present a novel speaker diarization system which is built following a bottom-up agglomerative clustering approach and based on speaker binary keys, recently proposed for speaker modeling. After initialization, processing is entirely done over binary vectors and using exclusively binary metrics, which makes the system very fast. On tests performed using all conference meetings datasets released for the NIST RT evaluation campaigns we achieve diarization error rates just slightly worse than a classic acoustic-based system while running over 10 times faster.

Abstract: Large scale Online Social Networks (OSNs) like Facebook and Twitter are hosted out of multiple geo-diverse data centers to provide low latency and high fault tolerance. Such geo-diversity creates large amounts of WAN traffic for maintaining the consistency of replicas at different locations. Despite the dropping price of WAN bandwidth, the growth rate of OSNs combined with the incorporation of media rich long tail content (including images and videos) makes WAN traffic costs an increasing concern for OSN operators. At the heart of the problem lies a tradeoff between consistency and WAN bandwidth cost. In this paper, we propose the "Wait Your Turn"; WYT system that optimizes the tradeoff by leveraging: (i) knowledge of mapping between social relationships and geographic location, and (ii) knowledge of timing regularities in end user activity patterns. We quantify the benefits of such an OSN-aware update propagation strategy through a trace-driven analysis and show that it reduces WAN traffic by 55% compared to an immediate update of all replicas, while having minimal impact on consistency. Furthermore, for a given budget for WAN bandwidth, WYT increases consistency by several orders of magnitude compared to FIFO scheduling of updates.
